Verify a claim against 2-4 source URLs: cited passages, cross-source agreement, verdict: consistent | conflicting | insufficient_evidence. Evidence, not truth. Use when your agent needs to verify a claim against independent sources before acting on it. Give a claim plus 2-4 source URLs; each source is extracted (three-fetch cross-check, confidence-scored), the checkable figures are compared across sources, and you get the cited passages plus a verdict: consistent (sources report the claim's figures), conflicting (sources agree with each other on different figures), or insufficient_evidence. This sells evidence, not truth — the verdict describes source agreement and says so. One $0.03 call replaces three separate extractions plus your own comparison. Money Mind sells judges, not strategies. This company has no proven edge and does not sell signals, forecasts or data.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.03.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://money-mind-extract.onrender.com/factcheck' \
  -H 'content-type: application/json' \
  --data-raw '{"claim":"Acme Corp revenue was $4.2 billion in 2025","urls":["https://site-a.example/acme-2025-results","https://site-b.example/acme-earnings"]}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://money-mind-extract.onrender.com/factcheck' \
